Crawling through the tunnel encourages muscle development in young ones, and the bright colors and long tunnel are sure to stimulate the imagination during playtime. The I See You Tunnel is also compatible with a variety of tunnels and tents from Pacific Play Tents, so children can use the I See You Tunnel as part of a kid-sized play village. Our testers found the I See you Tunnel to be fun and well-built. The poping up animal tunnel sets up instantly, thanks to the springy steel structure, and the padding on the interior makes crawling through the tunnel comfortable and safe.
